Permanent Site: H1 East Transect; Depth: 5.9 Meters (19.5 Feet); Distance from river mouth: 2.4 Kilometers (1.5 Miles) east; Pre/Post Dam Removal: 6 years post-dam removal; Lat/Long: 48.1479177,-123.53472865; Site Description: This is a shallow site and one of the farthest removed from the effects of the sediment plume outside of the control sites.

This 3D model of the lava lake at Kīlauea's summit was constructed from a series of thermal images acquired during an overflight on Thursday, March 16. For scale, the lava lake is about 250 meters (820 ft) across. The lake is within the Overlook crater, which is within Halema‘uma‘u Crater.

The distribution of water on the landscape influences many ecological functions such as the distribution of vegetation, soil development and the cycle of chemical nutrients. All of these functions are subject to change as a result of variations in the duration of soil water saturation and flow of water through the distributed channel networks of watersheds.

On February 24, 2017, Nick Stasulis (Data Section Chief of the USGS New England Water Science Center, Maine Office) met with police and fire officials from the City of Bangor and surrounding communities to ride along with the US Coast Guard on the ice breaker Bridle.

VIDEO: Kīlauea Volcano's Kamokuna ocean entry. Today, the "firehose flow" could be clearly seen from the public lava viewing area, 800 meters (about one-half mile) east of the ocean entry, in Hawai‘i Volcanoes National Park.

VIDEO: The section of sea cliff above the ocean entry collapsed today at about 12:55 p.m. The sea cliff had become increasingly unstable as a large crack 5–10 m (16–33 ft) inland of the ocean entry had more than doubled in width, from 30 cm (1 ft) to 70 cm (2.5 ft), over the past several days.

What does it take to become an ocean engineer? Here is the path that USGS Gerry Hatcher took.
 

Residents and visitors both revel in Kauai’s lush landscape, and beneath its seascape. However, it’s underwater where things don’t look so healthy. Scientists from the U.S. Geological Survey put together a detailed picture of the physical environment of the coral reefs at Makua Beach.

This video clip shows the open lava stream pouring into the ocean. Frequent littoral explosions throw bits of lava to heights of over 27 m (30 yards).

The open lava stream continues at the Kamokuna ocean entry. Today, the stream was remarkably steady, but produced pulsating littoral explosions where the lava impacted the water.

A presentation on "Unusual Sources of Tsunamis From Krakatoa to Monterey Bay" by Eric Geist, USGS Research Geophysicist

- Not all tsunamis are generated by earthquakes.
- Tsunamis can be caused by volcanoes, landslides, and even atmospheric disturbances
- Data from tide gauges can help unravel the complex physics of these sources

This video clip shows the lava stream - about 1-2 m or yards wide - pouring out of the tube into the Pacific Ocean, triggering pulsating explosions that are throwing bits of lava onto the top of the sea cliff.

The June 2016 Fish Fire burned over 12 km^2 in Los Angeles County, California. After the fire, the USGS installed an automated rain-triggered camera to monitor post-wildfire flooding and debris flow in a small canyon above the Las Lomas debris basin in Duarte. This video shows the peak flow triggered by an intense rainstorm on January 20, 2017.
 

This video clip shows spattering that was active along the southeast margin of the lava lake in Halema'uma'u Crater at Kilauea's summit. Rising lava levels over the past day provided improved views of the lake surface from the Halema'uma'u Crater rim (closed to the public due to ongoing volcanic hazards).
